SSBFECFCATEQN forming part of Letters Patent No. 311,784, dated February 3,1885.

Application filed April 19, 188i.

To all'wtcm it may concern.-

Be it known that I, RICHARD H. REILL', a resident of the city, county, and Stat-e of New York, have invented a new and useful Im- 5 provement in Louvers for Skylight-Turrets, Clear-Stories, &c., of which the following is a specification.

The object of :my invention is, iirst, to provide for effectual ventilation at all times in 1o skylight-turrets, clear-story openings, Src. second, while securing ventilation, to exclude rain, hail, or snow from the interior of the structure without excessive cost, and, third, to render the louver easy of transportation;

15 fourth, to provide snow orstorm proof louvers which will not retain water in any part thereof, to freeze up and create leakage, promote rust, or otherwise inj uriously atleet the effect ual. operation of the louver as a ventilator, and, lifth,to provide louver-slats which any ordinary workman can put into a structure without much labor.

The nature of my invention consists in providing louverslats with npward-extendin g flange at top and downwardextending flange at bottom, said flanges scalloped, perforated, or otherwise out that escape of air will be provided for, and each. louversla-t rest one upon the other, the points of contact being the outer edges of the aforesaid iianges, and aseries being thus put together into an opening without necessity of solder or rivets, although where eXtra strength is desired they or either may be used.

It also consists in providing` a chamber within louvers having inlet and outlet apertures through the chamber-walls, the shape of the chamber and position of inlet and outlet apertures being such that two reversed turns must be taken by rain, hail, or snow within said chamber between the apertured walls before it can reach the interior of the building, thus very effectual] y providing against any intlow of snow, hail, or rain during indriving storms.

In the drawings accompanying, Figure l Ais a front elevation of turret or clearstory wall provided with louver-s. Fig. 2 is a horizontal section of the same. Fig. 3 is a cross-sec tion vertically through the louver-s, with par- 5o tial perspective showingy one form. Fig. 4 is a vertical cross-section and partial perspective of another form. Fig. 5 is a vertical cross-I section and partial perspective of another form. Figs. 6, 7, and 8 show Ain cross-section 55 a separate louver-slat of each ofthe forms respectively.

These forms are alike in principle, differing only in bends, and as they, when united, accomplish the same results, they are equiva- 6o lents.

Arrows on the drawings show the direction of the outgoing currents from the building.

A is the base of the turret, B the transom,

C the posts. t 6

D represents the louver slats, of which there maybe any number in the series superposed, all in contact, each supporting the other.

E isun upward-extending iiange 'to the slat, 7o and F a downward-extending flange. These iianges are perforated, or what I deem better, have their edges cut into and a portion removed, so that when in position apertures will be provided for the escape of vitiated air from 75 therbuilding. G and G represent such apertures, several shapes being shown on the drawings. Then several of these slats are superposed, a chamber, H, is formed between them, through which the escaping air must 8o pass outwardly, and through which in an opsite direction all hail, rain, or snow must pass before it can reach the interior of the building, as well as through the apertures formed in the dang-es E F. In the passage such in- 85 driving material must make two (at least) complete revolutions. It will readily be seen that it would be very unlikely that such should ever make the complete passage. All water which from any cause may reach the interior 9o chamber, H, will readily i'low down over the face of the lower louver and away7 from the structure, the slats and chamberbeing so constructed as not to retain foreign matter within or about them. rlheir shape is such, also, that 9 5 they may be set together, like sheets of paper,

and transported safely to any/'destination with! upon the other by said fling-es, substantially out Waste of space in packing. as shown and described. A
